Filigran Accelerates U.S. Growth with Strong Revenue Surge, Enterprise Adoption, and Platform Innovation
European cybersecurity firm Filigran has reported significant momentum in its U.S. expansion efforts, underscoring its emergence as one of the fastest-growing players in the global cybersecurity landscape. As the company heads into RSA Conference 2026, it has announced a series of milestones that highlight both commercial success and technological advancement.
Over the past year, Filigran achieved nearly fourfold growth in North American annual recurring revenue (ARR), signaling strong demand for its solutions among enterprise and government customers. The company also onboarded 29 new clients across critical sectors, while continuing to enhance its platform capabilities with the general availability of OpenAEV Enterprise Edition. Together, these developments position Filigran at the forefront of a rapidly evolving cybersecurity market.
A Market Shift Toward Proactive Cyber Defense
Filigran’s growth reflects a broader transformation in how organizations approach cybersecurity. Traditional models, which rely heavily on reactive alert handling and incident response, are increasingly being replaced by proactive strategies that focus on identifying and mitigating risks before they can be exploited.
This shift has been accelerated by the growing adoption of Continuous Threat Exposure Management (CTEM) frameworks. CTEM emphasizes continuous assessment of an organization’s exposure to cyber threats, enabling security teams to prioritize actions based on real-world risk rather than theoretical vulnerabilities.
Filigran’s Extended Threat Management (XTM) platform is specifically designed to address this need. By integrating threat intelligence with adversarial exposure validation, the platform provides organizations with a unified view of their security posture. This approach allows teams to move beyond isolated tools and workflows, enabling faster and more effective decision-making.
Samuel Hassine, co-founder and CEO of Filigran, has emphasized that the core challenge facing security teams today is not a lack of data, but the inability to translate that data into actionable insights quickly enough. His perspective reflects a growing consensus within the industry that speed and integration are critical to effective cyber defense.
Enterprise Adoption Across High-Security Sectors
A key driver of Filigran’s growth has been its ability to secure customers across a wide range of high-security and regulated industries. In the United States, the company has expanded its footprint among financial institutions, federal agencies—including the Federal Bureau of Investigation—healthcare providers, technology companies, aviation firms, and retail organizations.
This diverse customer base highlights the versatility of Filigran’s platform and its ability to address complex security requirements across different operational environments.
Globally, Filigran’s solutions are trusted by major organizations such as the European Commission, Capgemini, Bouygues Telecom, EDF, and ASRG. These partnerships underscore the company’s credibility and its ability to operate at scale in mission-critical environments.
Filigran also reported a net revenue retention rate of 119%, indicating that existing customers are not only maintaining their subscriptions but also expanding their use of the platform. This level of retention is a strong indicator of customer satisfaction and the platform’s long-term value.
Demonstrated Impact: Real-World Results
The effectiveness of Filigran’s platform is reflected in measurable outcomes reported by its customers. Electric vehicle manufacturer Rivian, for example, implemented Filigran’s solutions across its cybersecurity operations and achieved significant performance improvements.
Within a 12-month period, Rivian reported a 95% improvement in response times and an 88% reduction in mean time to detect (MTTD) threats. These metrics demonstrate the tangible benefits of integrating threat intelligence with operational workflows, enabling faster identification and mitigation of risks.
Cybersecurity professionals within organizations have also highlighted the efficiency gains delivered by Filigran’s tools. By streamlining processes such as threat analysis and incident management, the platform allows teams to handle higher volumes of cases with greater speed and accuracy.
Industry leaders have further reinforced this perspective, noting that the ability to convert intelligence into decisive action provides a critical competitive advantage. Filigran’s customer-centric approach, combined with its focus on actionable insights, has been widely recognized as a key differentiator in the market.
Industry Recognition and Independent Validation
Filigran’s rapid growth has not gone unnoticed. The company has received multiple forms of independent recognition, further validating its position in the cybersecurity ecosystem.
It was ranked among the top 30 companies in the 2026 Cyber 150 list, an independently compiled ranking of the fastest-growing midsize cybersecurity firms. The ranking is based on objective metrics such as headcount growth, ensuring an unbiased assessment of company performance. Filigran’s inclusion for the second consecutive year reflects its sustained momentum and strong organizational growth.
In addition, its OpenCTI platform was named a Leader in the G2 Winter 2026 Threat Intelligence Grid® Report. This recognition is based on user feedback and market presence, highlighting both the platform’s technical capabilities and its adoption among customers.
Platform Evolution: From Intelligence to Action
Filigran has continued to expand the capabilities of its XTM platform, evolving from a focus on threat intelligence to a more comprehensive approach to cybersecurity.
One of the most significant developments is the release of OpenAEV Enterprise Edition. This solution represents the industry’s first open-source platform for threat-informed adversarial exposure validation. By integrating with OpenCTI, OpenAEV enables organizations to simulate attack scenarios based on real-world threat intelligence and frameworks such as MITRE ATT&CK.
This capability allows security teams to test their defenses across multiple dimensions, including technical systems, human behavior, and business processes. By closing the loop between insight and remediation, organizations can continuously improve their security posture.
Filigran has also introduced major enhancements to OpenCTI, including expanded artificial intelligence capabilities. These updates enable automated ingestion of threat data, natural language querying through chatbot interfaces, and more precise prioritization of threats based on geographic and industry-specific factors.
Building a Community-Driven Ecosystem
A defining feature of Filigran’s strategy is its commitment to open-source development. The company’s OpenCTI platform is used by more than 6,000 organizations worldwide, supported by a vibrant community of over 6,500 members.
This ecosystem includes more than 300 integrations developed by both Filigran and its community, creating a flexible and extensible platform that can adapt to a wide range of use cases.
The open-source model provides several advantages, including transparency, flexibility, and the absence of vendor lock-in. At the same time, enterprise customers benefit from additional features such as SaaS deployment, dedicated support, and advanced analytics.
This combination of community-driven innovation and enterprise-grade capabilities has proven to be a powerful differentiator, enabling Filigran to compete effectively with purely commercial solutions.
Scaling Operations to Support Growth
To sustain its rapid expansion, Filigran has made significant investments in its workforce and operational infrastructure. Over the past year, the company increased its U.S. team by 77%, bringing its North American headcount to 43 employees.
Notably, Filigran reported zero voluntary attrition during this period, reflecting strong employee engagement and organizational stability.
The company has also strengthened its leadership team with the appointment of Dave Giles as Chief Customer Officer. In this role, Giles will focus on enhancing customer success and ensuring that clients derive maximum value from Filigran’s solutions.
On the partnership front, Filigran has adopted a partner-first go-to-market strategy. This approach has driven a 200% increase in partner-attached revenue and resulted in the addition of 35 new channel and technology partners worldwide.
Looking ahead, Filigran is well-positioned to build on its recent success. The company has raised more than $100 million in total funding, including a $58 million Series C round led by Eurazeo, with participation from Deutsche Telekom, Accel, and Insight Partners.
This financial backing provides the resources needed to continue investing in product development, market expansion, and talent acquisition.
Key priorities for 2026 include further growth in North America, continued enterprise adoption, and expansion into new international markets such as Japan. The company also plans to deepen its platform capabilities, particularly in areas related to AI-driven security and proactive risk management.
With strong revenue growth, expanding enterprise adoption, and continuous innovation, Filigran is establishing itself as a major force in the cybersecurity industry. Its focus on proactive defense, combined with a robust open-source ecosystem and advanced platform capabilities, positions it well to address the evolving challenges of modern cyber threats.
As organizations increasingly prioritize resilience and risk reduction, Filigran’s integrated approach offers a compelling solution—one that not only identifies threats but enables organizations to act on them with speed and confidence.
